 For example, on a set of 1450 cc/min injectors running on gasoline with a 2.0L 4-cylinder engine, you'd expect to idle in the 1.6-1.7 ms range. ​ And as you can see in the next section, the behavior of any given injector down in that range can be very different from the behavior in the 2ms range. ​ It doesn'​t sound like much of a difference, but it can be as much as a 30-50% difference in some areas. ​ That's huge!  That's like having one cylinder running at 14.7:1 and another running at 9:1 with the __same__ pulsewidth. For example, on a set of 1450 cc/min injectors running on gasoline with a 2.0L 4-cylinder engine, you'd expect to idle in the 1.6-1.7 ms range. ​ And as you can see in the next section, the behavior of any given injector down in that range can be very different from the behavior in the 2ms range. ​ It doesn'​t sound like much of a difference, but it can be as much as a 30-50% difference in some areas. ​ That's huge!  That's like having one cylinder running at 14.7:1 and another running at 9:1 with the __same__ pulsewidth.

-To be clear, this behavior isn't specific to the FIC BM1450s. ​ Every injector set out there can have this problem to varying degrees. ​ We're forcing these injectors to operate in an area where they were really not intended to produce precise flow.  Basically, we're using the injectors in an application where they weren'​t ​designed ​to be used.  So we have to pay a little extra attention to the details.+To be clear, this behavior isn't specific to the FIC BM1450s. ​ Every injector set out there can have this problem to varying degrees. ​ We're forcing these injectors to operate in an area where they were really not intended to produce precise flow.  Basically, we're using these injectors in applications ​they were not designed ​for.  So we have to pay a little extra attention to the details.
